Determine the percent ionization of a 0.230 m solution of benzoic acid.
Fudgin [204]
We need the dissociation constant of benzoic acid which is 6.3x10^'5. Then using the dissociation formula, ka = x2 / (Mo - x) where Mo is the initial concentration. x is determined then. percent ionization is computed as (x/Mo)* 100%. This is then the final answer.

What is the net ionic equation of the reaction below?
faltersainse [42]

Answer:

Net ionic equation:

 Ca⁺²(aq)  + CO²⁻₃(aq)     →   CaCO₃(s)

Explanation:

Chemical equation:

K₂CO₃  +   CaCl₂    →   KCl  +  CaCO₃

Balance chemical equation:

K₂CO₃(aq)  +   CaCl₂(aq)    →   2KCl(aq)  +  CaCO₃(s)

Ionic equation:

2K⁺(aq) + CO²⁻₃(aq)  +   Ca⁺²(aq)  + 2Cl⁻(aq)  →   2K⁺(aq) + 2Cl⁻(aq)  + CaCO₃(s)

Net ionic equation:

CO²⁻₃(aq)  +   Ca⁺²(aq)      →   CaCO₃(s)

The K⁺(aq) and Cl⁻ (aq) are spectator ions that's why these are not written in net ionic equation. The CaCO₃ can not be splitted into ions because it is present in solid form.

Spectator ions:

These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equatio n.
